METAR wind direction is reported with respect to which north?

Explanation:
METAR wind direction is expressed as the direction from which the wind is blowing, measured relative to true north. Using true north provides a consistent, worldwide reference because magnetic variation changes with location and over time, which would make wind directions ambiguous if magnetic north were used. So a wind from 270 degrees is blowing from the west, regardless of where you are. While runway numbers are based on magnetic north, the wind direction in METARs uses true north, not magnetic bearing. Geographic north is essentially the same reference as true north, but the standard METAR practice explicitly uses true north.
